GCE define egress ip accross regions

There is a compute engines that is located in a specific region e.g. us-east. Now I want this compute engine to recieve an egress (not ingress) external ip adress from another region e.g. eu-west.

I know I could create a forward proxy for such a usecase but I am wondering if this also possible with gcp tooling.

File and Printer Sharing disable config

I disabled the File and Printer Sharing feature over the firewall on the windows server to which my abc.com website is connected. This server only hosts website and mail.

When I ping abc.com on cmd after Disable, request timed out appears, this is what I wanted, but can this setting turn off something else?

What is the best practice for this on the server?

I've been trying to read up on the details of drops as they are reported by various tools (and at various levels) of the OS. So far, most of the info I've been able to dig up by googling seems rather "hand-wavy" to me.

First, let me state that the example host I'm looking at shows ZERO drops in /proc/net/softnet_stat. This indicates to me that NIC ring buffers are probably sized adequately. Now, onto

The Stunning Power of Questions

Much of an executive’s workday is spent asking others for information—requesting status updates from a team leader, for example, or questioning a counterpart in a tense negotiation. Yet unlike professionals such as litigators, journalists, and doctors, who are taught how to ask questions as an essential part of their training, few executives think of questioning as a skill that can be honed—or consider how their own answers to questions could make conversations more productive.

That’s a missed opportunity. Questioning is a uniquely powerful tool for unlocking value in organizations: It spurs learning and the exchange of ideas, it fuels innovation and performance improvement, it builds rapport and trust among team members. And it can mitigate business risk by uncovering unforeseen pitfalls and hazards.

For some people, questioning comes easily. Their natural inquisitiveness, emotional intelligence, and ability to read people put the ideal question on the tip of their tongue. But most of us don’t ask enough questions, nor do we pose our inquiries in an optimal way.

The good news is that by asking questions, we naturally improve our emotional intelligence, which in turn makes us better questioners—a virtuous cycle. In this article, we draw on insights from behavioral science research to explore how the way we frame questions and choose to answer our counterparts can influence the outcome of conversations. We offer guidance for choosing the best type, tone, sequence, and framing of questions and for deciding what and how much information to share to reap the most benefit from our interactions, not just for ourselves but for our organizations.
